User oversight; MODEL deleted preventing users from logging on which coincided with VIO filling up.
If a USER NOT FOUND occurs, check that the MODEL used for the users is still there. If not, then the FAQSUTIL INIT PW has to be run to rebuild it.
Then use "SCTY CONFIG"
and
Set the "Use SCTY entry not only profile ( X )" field.
